In Japan, convenience is king and getting tested for COVID-19 can be highly inconvenient. Part of the solution, as it is for a range of daily necessities in Tokyo, has become the humble vending machine.

Eager to conserve manpower and hospital resources, the government conducts just 40,000 polymerase chain reaction (PCR) tests a day, a quarter of its capacity, restricting them to people who are quite symptomatic or have had a high chance of being infected.

That's led to the public to rely heavily on private clinics or buying PCR tests by other means.
